The Third Servile War was over. The slave army had been defeated, and their Roman captors offered the survivors a pardon. The only requirement was that they identify Spartacus, their leader (a sun-bronzed, cleft-chinned Kirk Douglas).

Rather than give away his identity, however, each of them cried out “I’m Spartacus!”—thus preserving his anonymity. The Romans could not identify him; they could not discern which of the men standing before them had been the leader of the rebellion.
